1 Better method to install solderless compressionconnectors on power cableThe Thomas & Betts method of installing compression connectorson power cables is designed to provide a high degree ofreliability in electrical wiring. This method allows electrical workers to make installations withlittle effort and considerable savings in time. The Thomas & Bettsmethod is a simple three-step installing procedure that utilisesColor-Keyed connectors and dies with compression typeinstalling three steps First, the appropriate connector is chosen for the conductorsize Next, the proper installing die is selected by matching thedie colour to the connector colour Last, the die is installed in the tool, and the connector conductivity electrolytic copper Excellent electrical conductivity thanks to lowest electrical resistance.

2 Associated to superior tensile strengthTubular constructionNo seam, ensuring excellent mechanical propertiesElectro-tin platedEnhanced corrosion resistanceColour-coding according to the cross-section of the cable,Easy selection of the connector, the die and the tool according by marking the connector with coloured rings and to the size of the cablewith the name of the colour Higher level of reliability Die-code engraved on the surface of the die Easy and reliable inspection SpecificationsAccording to DIN and ULAir compression by the T&B Method, the cross section looks like this,100% metal with virtually no air spaces.

3 Before compression, a typical cross section of cable and connectorconsists of about 75% metal and 25% Color-Keyed system from Thomas & Betts tellsyou where to place the installing dieColor-Keyed connectors not only identify the correct installingdie to be used for positive compressions, but also indicate theproper placement of the die on the connector. This is done bythe coloured rings around the connector which match thecolour on the dies. Compression is made between or on thesecolour bands. The colour name is also spelled on the connectoras an added means of die is positioned between colour bands for copper connectors andon the bands for aluminium dies form a solid, homogenous mass The Thomas & Betts method utilising compression tools withmatching dies forms the connector and conductor into a solid,homogenous mass to provide an optimum electrical bondbetween connector and conductor.

4 Color-Keyed dies are designed to produce a circumferential,hex- or diamond-shaped compression rather than a simpleindent. Precision dies are an integral part of the Thomas & Bettsmethod. Each die is designed so that all conductors receive the sameamount of compression force. The circumferential compressioncreates a large area of high pressure contact between cable andconnector which, in turn, assures high conductivity, lowresistance, and high pullout values which exceed features result in a permanent, low installed costconnection.
